Abstract

The invention relates to the technical field of separation of chemical products and specifically relates to a dirty oil sludge decomposition method. The decomposition method comprises the steps of firstly adding clear water into a treatment tank, preheating to 70-100 DEG C, adding dirty oil sludge, stirring, and performing heat preservation for 20-60min at the temperature of 45-75 DEG C to fully emulsify the dirty oil sludge; further adding a separating agent, uniformly stirring with the dirty oil sludge, reacting with the dirty oil sludge under heating conditions to thoroughly separate oil, sludge and water, extracting upper-layer petroleum ingredients, and performing harmless treatment on the remaining sludge and water. The invention aims at providing a dirty oil sludge decomposition method with low cost and little pollution.

Description

technical field [0001] The invention relates to the technical field of separation of chemical products, in particular to a method for decomposing sludge. Background technique [0002] Sludge is a viscous semi-fluid oily pollutant separated from petroleum during oil extraction or refining. The current treatment method for sludge is usually to heat the sludge, then add a separating agent, settle and separate, obtain oil, and discharge sewage and sludge. However, the used separating agents are usually non-ionic, cationic, anionic or their mixed surfactants, and excessive addition of these separating agents will cause water pollution. Contents of the invention [0003] The purpose of the present invention is to provide a method for decomposing sludge with low cost and less pollution. [0004] The solution adopted by the present invention to solve the technical problem is: a method for decomposing sludge. First, add clean water to the treatment tank to preheat to 70-100°C, th...
